Well certainly this will not be case. Say there are 5 lakhs in btc in India then after ban only 50k or so will be still doing it rest will get out since its being ban. Take an example of gambling currently what population of India does it and think once it get legalized it will increase manifolds.
Contradicting article. Ystd as per Newsbtc Govt has still Undecided About Bitcoin’s Regulatory Status.
http://www.newsbtc.com/2017/06/20/india-bitcoin-regulation-undecided/Bitcoin will not be banned in India. But I expect the Government to have strict laws and tax rate imposed on bitcoin traders as a measure to discourage people from dealing in bitcoin trading and investing activities. We will have to see how things will turn out.
